These Errata, realizations, etc. had the blessings of Eric Ewazen, who was present at the recording session when I recorded this piece. The are also based on the original manuscript from Eric Ewazen. I have also included places where I recorded passages down an octave, while using a 5.0 marimba.

1. This is my realization of the passage from m.s140-160. m.160 is the two important musical climax's of this piece, the other and very most important being m.229. The volume necessary to play the m.140 passage musically finds this solution more effective than using right hand independent rolls. My opinion.

2. last pitches of m.39 and 40 should be C-flat, not A-flat.

3. one might consider adding a low-E-flat on the last note of m.131, but very softly.

4. m.140 see above.

5. last note of m.151 should be A-natural, not A-flat.

6. m.163 play one octave lower.

7. play m.178 to the first note of m.193 down one octave. On the downbeat of m.193, the left hand notes are as written, and the right hand notes are down one octave. From the 2nd sixteenth note of m.193 place in the octave written.

8. In m.202, the order of the double vertical strokes is incorrect. If you label each stroke written from 1 to 6, the correct order is: 2,1,4, 3,5,6.

9. In m.237, the third double vertical stroke in the left hand should be low B and G-natural, not low B and F-sharp.

10. A few comments directly from Eric about the piece: "The chorale is the most important aspect of the piece. The basic chorale is in a minor key, giving it a melancholy sound. Sometimes it is more dissonant, and usually there is a sense of resolution. The piece grows from one section to another, getting more intense. Harmonically it is in a neo-romantic style. There is a focused use of dissonance. During the composition of the piece, his mother became terminally ill. She did hear the music before it was finished, and she commented on and enjoyed the chorales especially. Northern Lights: sparkling, shimmering colors,somewhat mysterious, but with beautiful mystery. Eric resumed and finished the writing of this piece after his mothers passing. The minor sounds took on a different character to him, serving as a reminder. C-sharp minor became more the focus, from C major. The final Allegro is to sum up all the previous material. The ending remains tonal, and ends more in the major tonality. The approach to resonance and texture is similar to the Mexican Dances. George Crumb said: "percussion is the basso continuo of the 20th century"."
